Abstract :
Power quality is a term to express the quality of current and voltage and increase reliability in the network. The quality of the voltage and current can be interpreted how close it is to the sine wave of a nominal size and frequency. The problem of quality of power produced by renewable energy sources has been analyzed for years. Power quality disruption factors in photovoltaic systems include current and voltage harmonics, frequency distortion, power fluctuations in solar sources, etc. In this paper using the genetic -ant algorithm to optimize proportional -charter controller parameters (PI), Improves three -phase modulation modulation signals (PWM) in the inverter (Q ZSI), which results in a reduction (THD) output, and not only reduces the overall inverter performance time, but also improves the key speed speed.
